7 Claims.

My invention relates to improvements in devices for use with overheadtrolley wire systems; and the objects are to provide an approach, endmember or tip which may be detachably secured to overhead devices ofvarious types and be readily replaced when worn and to provide acontinuous guide surface for current collectors passing from the wireonto the device to which the improvement is attached and vice versa.

I attain these objects by the construction illustrated in theaccompanying drawing, in which-- Fig. l is a side view of my inventionas applied to an-end portion of an overhead trolley device.

Fig. 2 is a top view of Fig. 1.

Fig. 3 is an end view of Fig. 1.

Fig. 4 is a side view of my improved end or tip shown in Fig. 1.

Figs. 5A, 5B, 5C, 5D and 5E show sections on the lines A, 'B, C, D and Erespectively of Fig. 4.

Fig. 6 shows a section on the line 6-6 of the tip shown in Fig. 1, afterthe lips shown in Fig. 5 have been formed about the trolley wire.

This application is a division of my co-pending application, Serial No.56,973, filed December 31, 1935.

In the preferred embodiment of my invention I provide a tip of metalhaving a tongue portion l adapted to be positioned in a slot or grooveforming part of the device to which the tip is attached. The tongue isprovided with transverse openings 2 to receive means for securing thetip in position relative to the attached device.

Projecting from the tongue I is a portion having a rib 3, and an opengroove 4 of varying depth formed by the bendable lips 5 and 6 varying indepth.

In Fig. 6 the lips 5, as for instance, at the sections CD, are shownclinched in position on the trolley wire I. It will be noted that'thelower edges of the lips meet a considerable distance below the trolleywire, thus leaving a space 8. This construction permits the trolley wireto be brought up over the end 9 of the device to which the tip isattached and at the same time the closed lower surface of the tip is inalignment with the lower edge of the trolley wire device to which thetip is attached, thus the trolley shoe or wheel makes a smooth anduninterrupted passage from the tip to the attached device and viceversa.

At section B, Fig. 4, the lips are of such length as to just encirclethe wire 1 which at E, Fig. 4, the lips 5 are spaced apart the diameterof the wire but the vertical direction of the recess within the lips ismuch greater as shown in Fig. 6.

The lips 6 shown in Fig. 5A are arranged to grip the trolley wire in thegrooves with which most trolley wires at the present day are provided.If, however, the wire is round or some other shape the lips will bearranged accordingly.

lips 5 and the construction of the portion bearing I the lips 6 are soarranged that the lower surface l I of the trolley wire I will be inalignment with the lower surface l2 of the lips when closed and will inturn be in alignment with the lower surface of the device to which thetip is attached. The end face l3 of the lips 5 abuts against the endface of the attached'device.

The lower face 14 of the tongue I is tapered to better correspond to theangle which the trolley wire will assume in its transition from the tipto the attached device.

The aforesaid trolley wire device is formed preferably of metal and hasintermediate its ends means to hold the wire in position.

Having disclosed my invention, I claim:

1. A tip for a trolley wire device comprising a body having a tongueportionto receive means for securing the tip to the device, a portionprojecting from the tongue in alignment with the tongue, one edge of theprojecting portion provided with a wire-receiving groove open throughoutits length along one edge, one portion of the groove formed by lips ofuniform depth and another portion of the groove formed by lips ofvarying depth, the lips of varying depth being adapted to have theirfree edges formed together to enclose the wire and form a guide surfacefor a current collector and also form a wire-receiving passage. ofvarying depth.

2. A tip for a trolley Wire device comprising a body having a tongueportion adapted to be at lips forming the other portion of the groovebeing bendable along their free edge to meet and form the last saidportion of the groove into a passage of tapering cross-section throughwhich the trolley wire passes.

3. A tip for a trolley wire device comprising a body having means forattachment to the device and means projecting from the attaching meansin alignment therewith, the projecting means being provided with spacedlips forming a groove open along one side only to receive a trolley wiretherebetween the lips decreasing in length along one end of theprojecting means towards the other end thereof and adapted to be bentinwardly along their free edge until the edges abut forming a passage oftapering cross-section between its ends to receive the trolley wire, the

passage being of the same dimension at one end as that of the wire andof a greater dimension at the other end in one direction than that ofthe wire but of the same dimension as the wire in the other direction.

4. A tip for a trolley wire device comprising a body having means forattachment to the device and means projecting from the attachment meansin alignment therewith, the projecting means being provided with spacedlips forming a groove open along one side only to receive a trolley wiretherebetween, the lips being of decreasing depth for a portion of thelength thereof along one end of the projecting means, the lipsdecreasing in depth toward the other end thereof and adapted to be bentinwardly along their free edge until the edges abut forming a guidesurface for a current collector and also forming a passage of taperingcross-section between its ends to receive the trolley wire, the saidguide surface being in alignment with the lower surface of the trolleywire held in the groove of the said first portion.

5. The combination with a trolley wire of a supporting tip for the same,the tip having means to secure it to an overhead trolley wire device andother means projecting therefrom, the latter means having an open grooveformed by spaced lips along one edge and in which groove the trolleywire may be placed, the lips being bendable about the trolley wire toenclose the same and the abutting edges of the lips forming a guide fora current collector, the passage formed by the bent lips having adiameter at one end equal to that of the trolley wire and having adimension in one direction at the other end greater than the diameter ofthe trolley wire.

6. A trolley wire device comprising a body member provided with agrooved end adapted to receive a trolley wire, a tip member secured tothe body-member and having a tongue positioned in the groove and thereinsecurely held, the tip member also having a projecting portion providedalong one edge with an open groove formed by spaced lips of varyingdepth adapted to receive the trolley wire, the lips arranged to beformed about the trolley wire after the wire is positioned in the grooveto form a passage within which the wire rests, the diameter of thepassage at one end being that of the wire and the other end of thepassage having a dimension greater in one direction than the diameter ofthe wire, the lower portion of the formed lips acting to guide a currentcollector from the trolley wire onto the said body member.

'7. A trolley wire support for application to a trolley wire withoutbreaking the continuity of the wire comprising an elongated memberadapted to form a part of an overhead system and to guide a movingcurrent collector over a portion of the system, means associated withthe elongated member intermediate its ends to engage the trolley wireand hold it in place, the elongated member having a clevis at one end toreceive the trolley wire and hold it in alignment therewith, detachablemeans having a portion positioned in the clevis and the other portionprojecting therefrom in alignment therewith to receive the trolley wireand hold it in alignment with the guiding edge of the said member, thedetachable means provided with a groove formed of bendable lips toreceive the trolley wire and the lips when bent forming a passage aboutthe wire of varying size whereby the wire is permitted to pass upwardlyand through the aforesaid clevis and the lower surface of the formedlips is in alignment with the guiding edge of the member and acts toguide the current collector from the wire onto the elongated member.
